Packaging with liquid lid for flowable fillers

A package for flowable fillers consisting of side walls walled with at least one longitudinal seal, which are coated with cardboard or the like and end walls arranged at the ends of the tube, the second end wall forming the lid of the package consisting of a thermoplastic fixed to the side walls and has a pouring device which can be turned inside the outer contours of the package, e.g. for transport, while the second end wall underlying the package is rectangular and has a transverse seal seam with a triangular strip folded on the adjacent wall.

The type of packaging currently most commonly used for the transport of liquids, especially milk and fruit juices, is a parallelepiped package consisting of a hose 20 of plastic-coated carrier on both sides closed at the ends in transverse barrier lines in the region of the end walls. there are two opposite, double-walled triangular strips projecting outwards mainly from the end walls of the package 25 and finally again folded against the adjacent side walls or end walls of the package.

Repetitive suggestions are being made for landfills and specifically for thermoplastic-coated paper, board, etc., coated on both sides, with perforated lines or other weakened lines and for packages with lids of plastic without carrier or other closures, vices, such.

35 Manufacturers of packaging for liquid substances in accordance with the definition of the species mentioned above strive for optimal plastic savings, 2 69809 simple manufacturing and filling machines, good tightness and easy opening. The package according to the invention relates both to the design and the use of the mold for the production of a package for liquid substances with a perfect seal and a good opening method, to a pouring device fitted to the lid, which, like the lid wall, consists entirely of thermoplastic without carrier. It is known to design a wide variety of pouring devices, and with regard to packages of liquid substances 10, it has already been proposed that the lid with the pouring device be injected into a form in which the user subsequently uses the package for pouring purposes. In spraying and until the next machining step during manufacture, the aim is the shape in which the lid is used, i.e. the shape in which the user opens the package, pours the fluid and possibly closes the package again. In this case, it is advantageous that the thermoplastic plastic, on the basis of its inherent tendency, wishes to return to the original injection form obtained during manufacture, if its shape has been changed in between. The mother can then, for example, reshape the lid from the transport position in which the pouring device was pushed inside the outer contours of the package into the injection mold given to the lid in manufacture by pulling and pressing it without having to apply very much force. If the package lid is sprayed into its mode of application, simple spraying tools can also be used.

The object of the invention compared to the known and proposed packages is to provide an even better package with a particularly suitable pouring device which makes opening easy, prevents overflow due to overflow or pressing of the liquid after opening, and is suitable for other practical purposes, e.g. aseptic filling and aseptic closure of baby food.

According to the invention, this object is achieved in that the lid has a cover wall which tapers outwards and upwards and leaves an opening in the middle, with a central edge, 3 69809 rising from the wall and a closure attached thereto. While simple manufacturing means can be used advantageously, the shaping of the lid according to the invention allows it to be opened well due to the fact that the lid folded out of the packaging position causes the volume of the package to increase, so that liquid leakage is avoided.

The opening of the cover wall can in principle also be located at the edge 10, i.e. not necessarily in the middle, but in mechanical engineering generally symmetrically shaped tools are used, so that fitting the opening in the middle of the cover wall is particularly expedient. The geometric shape of the cover wall is arbitrarily selectable, since it is possible to use injection molds of different shapes. The lid wall may be rectangular or round at its outer edge, so that its geometric shape may be like a pyramid or a box. However, it is particularly expedient for the lid to be round and for the tapered lid wall 20 to have a truncated cone-shaped annular surface in which the hinge edge is a truncated cone-shaped or cylindrical edge. The tools, and in particular the injection molding fashion, are most conveniently designed for such a cover. When using the shape of a truncated cone, the milk or fruit juice that may have accidentally spilled out may also run outwards so that the area of the lid remains approximately clean.

In a further development of the invention, a second flange is arranged on the outer circumference of the frustoconical annular surface, arranged to move inwards from the outer edge, in the shape of a cylindrical shell. This receives the free end of the tube closest to the lid and forms both a good fastening surface and a stiffening for the tube, so that the package according to the invention thus obtains the good strength shown. As a result, manufacture is also facilitated by the availability of geometrically well-defined and sufficiently large surfaces for the connection between a pipe made of plastic-coated cardboard on the one hand and a lid made exclusively of thermoplastic material on the other hand.

According to the invention, it is also preferred that the outwardly projecting outer edge of the lid completely covers the lid-side edge of the tube 5. It is when packaging liquids that the manufacturer tends to cover the cutting edges, which are no longer plastic-coated due to the cut, with pleats or other overlapping walls so that the liquid cannot penetrate and soften the carrier. If it is now advantageous to convert the flange into a cylindrical shape, as proposed in the invention, in order to form a shoulder 10, then the size of the shoulder can be shaped just firmly to receive the end of the tube. In this way, before connecting the pipe to the lid, the unprotected free edge of the pipe can be covered on the lid side by sealing it.

The invention is further characterized in that the frustoconical annular surface has at least one completely circular weakening groove, preferably inside the package. The reason that the inadvertent spillage of liquid remains in the grooves 20 is said weakening grooves preferably arranged to the side of the cover, which subsequently turned to the inside of the package. If the lid is completely round, the weakening groove is also completely round; if the lid is rectangular, the weakening groove may be shaped accordingly. The purpose of the weakening groove is to weaken the inner wall of the lid at that point: e.g. near the outer edge as well as near the cylindrical shell-shaped flange, so that the lid and its pouring device are inserted into the mode of transport after spraying and later against the end user. the injection form is facilitated. It is therefore appropriate to fit two concentric weakening grooves inside and out.

In addition, according to the invention, it is advantageous for the hinge edge to have an upwardly rising dome with a closure sealing the central opening, the closure preferably having a weakened extension of the dome wall and a handle attached thereto. A package with such a pouring device can also be shaped as a baby drink bottle, because the shape of the hood can be easily adapted to the shape of the suction part, i.e. the pacifier. At the uppermost point of the dome, which is thus furthest from the bottom of the package when the lid is extended in its operating mode, there is a weakened point in the last described embodiment which communicates with the proximal dome wall and the sprayed handle. This handle in the form of a strip, ring, plate or the like makes it possible to lift the package slightly, thus creating a pouring opening in the weakened point 10. This hole can be made as small as a pacifier or suction device so that the package can be used as a baby drinking bottle.

A package with a lid according to the invention is particularly expedient when the bottom of the package is in the form of a support base known per se, with a transverse seal seam and a triangular strip. As is known, such an end wall can be made from a rectangular shape to a tube-shaped shape by turning the triangular strips attached to the adjacent side wall upwards and then pressing the end of the package together.

When a package with a lid according to the invention has such a base structure, the baby can empty the contents by sucking even when no air is led from the outside into the package to replace the emptied liquid. Replacement is practically done only by squeezing the package, in the same way that toothpaste is removed from the tube by squeezing the end of the tube. To that extent, a package with a lid according to the invention is better than a glass baby drinking bottle.

30 Such packaging opens up new areas of application for the distribution of baby food in general and in the third world in particular.

Namely, it is still particularly advantageous if the ring surface with the dome according to the invention is pushed inside the outer contours of the package 35 and a cover plate is attached to the very outer edge of the lid, possibly aseptically sealing. Not only for relief purposes for those in need _______ .. - · i.

6 69809 food consignments, but also commonly used liquid baby food can be distributed aseptically by means of such a pouring device. For example, in connection with mass production, the sterilization of the lid wall can also be carried out as sterile as long-term. Tearing off the cover plate for use is as simple as possible and allows for extremely hygienic feeding of infants.

Other advantages, features and uses of the invention will become apparent from the following description of the preferred embodiments shown in the drawings. The drawings

Fig. 11 is a horizontal projection of the cover of Fig. 9 provided with an annular handle.

The finished package of flowable fillers shown here in Figure 1, in particular for milk, generally consists of side walls marked 15: 11, since this particular embodiment, which is repeated in other figures, has a circular cross-section in the area of the lid 2. However, due to the fact that the tubular side walls 1 in the region of the cover 2 have a completely circular cross-section, the four sides can be separated by an end wall forming the base 3.

For the final formation of the closed pipe, the sliding walls 1 are formed as a pipe and joined together along a longitudinal seal seam 4, which for the sake of simplicity is no longer shown in Figures 7-10. From Figure 4, the ha-25 stems that the longitudinal seal seam extends to the bottom 3. When the end of the tube is marked (at the edge) with 5, the outer edge 6 of the lid is observed on the opposite side, which thus forms the upper edge, i.e. the upper surface, of the overall circumferential lines of the lid transport mode (Figures 2 and 5).

The upper edge, i.e. the upper surface, of the finished package can be seen on the side 3 of the base from the line marked 7 in Fig. 4, where a double strip of cardboard 8 is also observed when forming the support base. Also shown here are triangular strips 10 which, in the situation shown in Fig. 4, machine on both sides of the base 3 are still flush with the base and are later folded into one of the adjacent sides and fastened to it.

8 69809

Before shaping the support base, the lid 2 is fixed in a liquid-tight manner to the lid-side edge 12 of the tube, i.e. the side walls 1 (Figures 3 and 6). Unlike the rectangular base 3, the lid 2 of the new package, which is preferably - but not necessarily - shaped, is made only of thermoplastic and without a carrier. The lid 2 is placed on the lid-side edge of the tube in a particularly clearly indicated manner and sealed to it. During this sealing, i.e. spraying, in which the lid, while covering the cutting edge 12 of the tube 1, is injected onto this edge 12, the lid 12 is in its mode of use, as shown in Figures 3, 6 and 7-9.

In contrast, there is a mode of transport shown in Figures 2, 5 and 10, in which the pouring device, generally indicated at 13, is folded inside the outer contours of the package so that no separate parts of the pouring device 13 protrude above the outer edge 6 of the lid 2. Thus, the correct stability of the package and good packability (with shrink films or the like) are guaranteed.

In the first embodiment according to Figs. The upper edge 15 is in the form of a closure, whereas in the embodiment according to Figures 5 and 6 the upper edge 15 is connected to the closure plug 16. In all embodiments there is a closed-welded gripping ring 17.

The shape of the first embodiment 30 of the lid 2 according to Figures 1-3 after injection is particularly clear from Figure 3. The outer edge 6 of the lid 2 is practically only a narrow ring, the outer edge 30 of which is moved inwards from the second cylindrical shell-shaped stop 18 as if it were a support part. so that the outwardly projecting outer edge 30 of the lid 2 completely covers the lid-side edge 12 of the tube 1.

9 69809

What has been said above also applies to the covering of the edge 12 according to Figures 5 and 6; only the outer edge of cover 2 is a wider shaped ring. In all embodiments, the upper side of the tube and its edge 12, and thus the upper edge of the side wall 1, will act as a support wedge for the stop 18. This ensures a particularly strong and rigid connection between the cover 2 and the side wall 1.

It is further found that in all embodiments of the cover 2 there is a cover wall 20, 10 tapering towards the center, which in particular is a frustoconical annular surface. The cover wall tapers outwards and upwards as a truncated cone-shaped annular surface. In the mode of transport according to Figures 2, 5 and 10, the truncated cone protrudes inwards at approximately the same angle.

Figures 1-3, 7 and 8 show that the gripping ring 17 is fastened by means of a thin fastening strap 51 to a wider, strip-like hinge 52, which in turn is formed by a truncated cone-shaped push edge 14. On the opposite side of the Kah strap 51 there is a gripping ring 17 20 with a washer 53 tightly fitted to the closure. The closure 13, in turn, is located above the annular line of weakness 54 at the top at the cam edge 14, as can be clearly seen in Figure 3. The connecting plate 53 protrudes (Fig. 3) radially the distance of the body over the upper edge 25 of the push edge 14, thus allowing a good chance of gripping it. On the opposite side of the connecting plate 53, the closure 13 is again fastened to the push edge 14 by means of a hinge 52. The hinge 52 forms a strong connection between the push edge 14 and the closure 13, but is flexible and allows the closure 13 to be turned up so that its edge 15 can be moved from the horizontal position shown in Fig. 3 when tilted, possibly even to a vertical position. In this context, good reclosability is also noted.

In the embodiment according to Figures 5 and 6, in this case, at the edge 15 of the cylindrical jacketed ridge edge 14, a point is marked 21 formed relatively strong when otherwise fitted with an annular line of weakness 22 in the same way as in the embodiment according to Figures 1-3. line 54. These lines of weakness 22, 54 extend as a weakened point almost 360 ° around the cam edge 14; e.g., as shown in Figure 6, around the closure plug 16 so that it can be easily torn off to open the package. In Fig. 6, next to the point marked on the left 22, there is an unmarked connection point of the gripping ring 17, next to which the vault 24 projecting inwards from the push edge 14 10 towards the center is arranged so that this vault 24 extends inwards according to Fig. 6 When the user then tears open the line of weakness 15 22 by tearing the gripping ring 17 (top according to Fig. 6), this first ruptures in the area of the vault 24, so that air can advantageously enter the space below the lid 2 after the package has expanded due to it that cover 2 is pulled up.

The embodiment according to Figures 1-3 does not have this 20 special vaults. In this case, it is sufficient for the user to tear the fastening tape 51, lift up the gripping plate 17 and tear the closure by means of the strip 53, rotating along the line of weakness 54 by a full 360 °. Pulling up the gripper 17 a second time ensures the inclination of the closure 13 or the edge 15 25 described above, so that the opening 34 is more or less completely open for pouring the filler.

In the embodiment of Figures 5 and 6, the hinge 25 of the closure plug 16 is located diametrically on the opposite side of the vault 24 of Figure 6, to the right of the closure plug 16 near point 21. The plug 16 can thus be moved around this hinge 25 in a clockwise direction. 16 without immediately coming out of the tear. Thus, also in the embodiment according to Figures 35 and 6, it is possible to close the package again, especially when the closure plug 16 has an edge 26 extending approximately to the push edge, which is closed only by the flat base 27.

1-8 embodiments of Figs can be seen that the frusto-conical annular surface 20 of the five-side cover 2, which is subsequently translated into the package interior of the two co-axial with matched to each other, fully circular weakening grooves 31 and 32 (specifically marked in Figures 3 and 6).

The embodiment according to Figures 7 and 8 differs from the embodiment according to Figures 10 to 4 only in the handle 55, which is arranged by means of a stiffening strip 56 placed on the package on the opposite side of the plate 53, i.e. on the hinge 52 side. The upper end of the gripper 55 is preferably close to the edges 12, 30. The push edge 14 with the closure 13 is otherwise of a structure previously explained in detail by means of FIG.

Figures 9-11 show a fourth embodiment of the lid 2, in which the pouring device is provided with an outwardly projecting dome 33 with a sealing closure 35 for the central opening 34. This closure 35 shows the wall of the dome 33 with a point weakening point to form the opening 34, the oval handle 17 11 is simultaneously injected into the closure 35.

Immediately after injection, the lid 2 takes on the shape shown in Figures 9 and 25 11, in which the annular lid wall 20 rises outwards and upwards.

When the closure 13 in other embodiments is only pushed inside the outer contours of the package for transport without further action, Fig. 10 30 shows a dotted line position with a cover line 36 shown in solid lines drawn just above the outer edge 6 of the lid 2. Thus, to open the package, the cover plate 36, which may be aseptically sealed, must first be broken and then the package 35 can be brought into use by gripping the ring 17 of the lid 2 and when the end user then further pulls the gripper 17 upwards until the opening 34 is open. , without the user being able to touch the surface of the dome 33 with his hand or otherwise soil it.

The user of the bottom end of the package is given a tubular shape by changing the package from the position shown in Figures 9 or 10 on the side of the base 3 in such a way that the triangular strips 10 are first folded up to the same plane as the base 3 (see Figure 4). The user then presses the corners in the transverse direction with respect to the double cardboard-10 layer 8, so that the rectangular shape becomes rectangular or even obtains the shape of the lower closure seam formed in Figure 4 by the double cardboard layer 8.
